TAMPA, Fla. 
Way before Prince, Paul McCartney or the Rolling Stones ever stepped onto a Super Bowl stage, there was Shirlee Bertolini. In her donkey costume.

So much has changed since she paraded around the Los Angeles Coliseum field for that very first halftime show.

Truth is, she wouldn't mind seeing things more like they were in 1967.

"We put on a band show. A fantastic band show," she said this week by telephone from Tucson, where she's in her 54th year as the University of Arizona's twirling coach. "You want to go to a concert, go to a concert.

"Now they're going to have Bruce Springsteen. So what? You could get a marching band, and it wouldn't cost you $10 million. I'm sorry, but that's ridiculous."

Will Bertolini watch The Boss and a cast of thousands in Sunday's extravaganza?

"I might," she said. "Or maybe I'll get up and have a beer."

In all ways, the Super Bowl has morphed from a curiosity to a behemoth.

A ticket cost $6 when Bart Starr, Vince Lombardi and the Green Bay Packers beat Kansas City 35-10 in that first game. The top ticket for this weekend's matchup between the Pittsburgh Steelers and Arizona Cardinals goes for $1,000.

Now, the game is by far the biggest sporting event in America, a semi-national holiday. But back then, before the original National Football League and upstart American Football League merged, many fans weren't sure how to view it. Or watch it, really, since CBS and NBC both televised the first one.

In fact, it was officially the AFL-NFL World Championship Game in the 1960s. Commissioner Pete Rozelle preferred "The Big One" but that got nixed. The late Lamar Hunt, among the AFL's founders, suggested "Super Bowl" as a temporary fix. He got the name idea after seeing his daughter bounce a SuperBall.

The halftime shows have mirrored that growth.

Even after Springsteen's "Born in the U.S.A" tour in 1984 made him a stadium smash, he kept his distance from the No. 1 sports show.

"Initially, it was sort of a novelty and so it didn't quite feel right," Springsteen said this week in Tampa. "It's a great spot now."

Springsteen said he began to change his mind after a random conversation.

"I was with a young musician one night at dinner and we got to talking about Super Bowls and he said, 'Hey, why don't you play the Super Bowl?'" Springsteen said. "He said, 'Man, I hope one day we're big enough to play the Super Bowl' and I got to thinking about that."

OK, it also helped that Springsteen and his E Street Band released a new album this week.

Top entertainers now covet the 12-minute Super Bowl spot, seen by nearly 100 million viewers in the United States and a worldwide TV audience.

Tom Petty & the Heartbreakers rocked last year in Glendale, Ariz. Sting, U2, Stevie Wonder and Britney Spears are among the other stars in the last decade. Janet Jackson gave the most memorable performance – her "wardrobe malfunction" in 2004 sparked a national debate.
